The Story Behind On's Cloudmonster: A History of Innovation

On, founded in 2010 in Zurich, Switzerland, is a relatively young brand that has quickly gained worldwide acclaim among top athletes and running enthusiasts.
The founders, former triathlon world champion Olivier Bernhard, along with David Allemann and Caspar Coppetti, set out with a clear vision: to create the sensation of "running on clouds."
The patented CloudTec® sole technology embodies this vision, combining soft landings with powerful take-offs to revolutionize running performance.
In recent years, On has expanded beyond running shoes, forming a high-profile collaboration with tennis legend Roger Federer and venturing into fashion-forward designs.
One standout result of this innovation is the "Cloudmonster" series.
Living up to its name, the Cloudmonster features oversized cloud pods that deliver unparalleled cushioning.
Combined with an advanced sole design, it’s built to reduce fatigue during long-distance runs, intense training sessions, and even casual urban walks.
This model exemplifies the blend of performance and style that has made On a global sensation.

Reasons Why Cloudmonster is Chosen: Functionality and Design

1. Outstanding Cushioning Performance with Large Cloud Pods

The standout feature of the Cloudmonster is its cloud pods, which are designed larger than those of standard models.
These large pods absorb impact during landing, providing a soft foot feel while also delivering exceptional rebound.
CloudTec® doesn’t just offer softness; during takeoff, it uses the energy from the pods returning to their original shape after being compressed, creating propulsion.
The enlarged pods further emphasize this energy return, delivering truly "monster-level" performance.

2. Smooth Movement with Rocker Shape

The sole design of the Cloudmonster features a gently curved rocker shape that complements the large cloud pods.
This design allows for smoother transitions of weight from the heel to the forefoot.
The rocker shape is a highly regarded concept in the running shoe industry, as it reduces strain on the ankles and knees, making it ideal for long-distance running or daily walking while minimizing fatigue.

3. Lightweight and Breathable Upper Material

At first glance, the Cloudmonster might seem bulky, but it actually features a lightweight and highly breathable mesh and synthetic fiber upper.
This design prevents overheating during runs, ensuring a comfortable environment for your feet.
Additionally, strategic reinforcements provide reliable support for extended activities.
The extensive use of mesh adds a sense of lightness to the overall appearance, doubling as a stylish design element.

4. Unique Silhouette and Design That Stands Out on the Street

While On's sneakers are generally known for their minimalistic and refined aesthetics, the Cloudmonster stands out with its strikingly voluminous sole design.
Retaining the performance of a running shoe, its bold silhouette also shines in street fashion, making it versatile for casual outings or urban lifestyles.
Unlike other On models, the Cloudmonster features daring print designs that serve as standout accents, enhancing its appeal for streetwear.
Additionally, it offers a wide range of color options, from understated monochromes to vibrant hues, allowing you to choose a style that best suits your personal preferences.

Experience the Comfort of the Cloudmonster

The flexible cushioning of the cloud pods might feel unique to those trying On shoes for the first time.
However, once accustomed, many report that the soft landings and responsive rebound become addictive, making other shoes feel lacking by comparison.
Additionally, the rocker shape ensures smooth weight transfer to the forefoot, providing exceptional comfort not only for long runs and walks but also for daily commutes and standing work, minimizing fatigue over extended periods.

Cloudmonster Size Review

A common observation with On shoes, including the Cloudmonster, is a slightly snug fit, especially in terms of width.
This design aims to minimize instability during runs, which is why some users feel the fit is tight.
Those with wider feet or higher insteps might consider going up by half a size.
Conversely, individuals with standard or narrow feet usually find their regular size to be a perfect fit.

Below are detailed size reviews based on actual staff experiences.

We hope these insights assist those unsure about their size selection.

Female Staff Review: Typically Wears 23.5cm in adidas SAMBA

The 23.5cm fit well in terms of width, but the toe area felt slightly tight.

Opting for 24cm provided additional room in the toes, making it ideal for sports use.

The insole features gentle contours, making it comfortable for those with flat feet.
The outsole curves towards the toes, encouraging forward momentum and ensuring an easy stride.

Male Staff Review: Typically Wears 26cm in adidas SAMBA

The usual 26cm size provided a perfect fit in both width and toe box.
The instep also had enough space, ensuring a comfortable experience, ideal for sports activities.

At 26.5cm, there was a slight increase in toe box space, which may suit casual wear better.

The 27cm size felt overly spacious, making it less suitable for walking comfortably. A true-to-size or half-size-up choice seems optimal.

Is Cloudmonster True to Size or Smaller?

Based on staff reviews and customer feedback from in-store fittings, the general consensus is to opt for true-to-size or half-size up, depending on individual preferences and foot shape.

If you're unsure about which size to choose, we recommend referring to the On Size Guide with staff reviews, which includes actual measurements of standard models.
